Yes, once again I am surprised by the amount of people out there that could have a serious medical problem and who refer to internet forums for an answer..when you stand up, you have less blood pressure (less than normal) to your brain you see dark spots, have light headedness and probably a fealing of fuzzy warmth in your head. GO SEE YOUR DOC. I am serious about this other condition and managed to leave out a very important question Natural light (or) electrical generated radiation? Inside (or) outside and sorry for the glob thing, it was underhanded!

Anybody game? Name Clayton lights are specks yes lights are all the same size yes lights are globs yes lights are erratic yes lights have pattern no Appear/dissapear yes Prior/current eye condition Good 20/20 Sex M Age & onset 29 & 22 Race Cauc Rural/Urban <14yr R >=14 U Work involve magnetic flds yes Other conditions/notes Typ1 Diab just cut and paste, then change answers. Could be good for a laugh if nothing else. or add some of your own ideas (so long as none are erased)

Hi Di13. Black? No, not mentioned! Snow? OK clayts

Hia Guys...me again! Luxnor, that sounds like low blood pressure to me!. You should probably seek medical attention if it happens all of the time. I have this web site bookmarked and am still trying to find an exact match. Can anybody out there see bright specks of light that do not follow a defined pattern of which they can concentrate on (with back and foreground distractions) until the time they dissapear. the ability to see the distance is a biggy. It is not two dimensional, it is four! fourth being time of course. I'm about to give up. I have already had a hissy fit on-line (which I'm not proud of). Think I will simply continue to monitor this page for now. GaryLeo I think has decided on the white blood cel idea. Nobody elses description comes close to what I get. So please drop a line if you do as I would like to set up a definition list male/female/age/country/onset age/race/background/work etc etc ...to get to the bottom of this for good. Clayts

OK, On second thought, this is possible and it only seams reasonable that it is the cause. I am sorry for my former attitude. I did not mean to come across as rudely as I did! The reason I was a bit cranky is because there are a few factors that don't add up. I'll just mention one such as your comment "you can often see the white blood cells moving in your blood vessels". One reason why I have a problem with this is because what we are aware of, are brite specks that are moving randomly and are constantly visable from the time they appear until the time they dissapear (they don't head towards the sides or flow in any defined way).They are not of constant speed. wouldn't this mean that all those vessals carring that blood would have to be arranged in a manner that resembles something like a stealo (wire scrubbing pad), you would have hot spots everywhere or maybe even a blockage (even a pop). I thought that blood follows specific paths...or in other words goes where and at whatever quantity and pressure that the overall resistance, or that the size and condition of the vessals will allow. so wouldn't it make sense that these paths in your retina would be fine oiled almost tree like structures and not one great short?. You also go on and add "because they are moving rather than fixed in position on your eye". So are you saying that because we are not focusing our eyes at anything in particular, the photoreceptors are looking that much harder for any change in the scene that they work harder, to the degree of picking up the white cels moving in the jittery yet relative retina.?? I'm having troubles with this idea. The cels are bigger, dunno, maybe but THAT BIG? Theres more than this but I will leave it here, I have to make dinner ) I don't expect a reply really after my last post, but I don't what people to fob this effect or whatever it is off !!!or to discourage open-mindedness towards other explainations.

Yeah.. I thought I had actually found the answer for a second there. If you are interested in listening to an under grads lighting conclusion which ...oh my... is very professional sounding then read the following Submitted by Angela, an undergraduate student from Pittsburgh, Pennsylvania, and Kris, from Chevy Chase, Maryland What are the moving spots I see when I look at a clear, blue sky? Why do I see a "ghost" image after I look at a bright flash of light? Provided by Jennifer F. Linden, postdoctoral fellow, University of California–San Francisco (former HHMI predoctoral fellow) Moving Spots The retina in humans (and all other vertebrates) is actually "upside down"—that is, the photoreceptors are at the back of the retina, and the blood vessels, at the front. (Interestingly, the retina in invertebrates, such as the octopus, is similar in structure but "right-side up.") Therefore, light reaching your photoreceptors has to travel through your blood vessels (and a couple more layers of neurons) first. You might think that this should mean that you would see your blood vessels and other retinal neurons in your vision all the time, but in fact you don't, because your photoreceptors are designed to detect changes in the visual scene. Your eyes are making very small movements (jitters) all the time. Even when you think you are looking steadily at something, the image of the object is actually moving slightly on your retina so that your photoreceptors can detect it. But the blood vessels and neurons are truly fixed on the retina, so your photoreceptors adapt to the light levels filtered through them and do not respond to their image. When you are looking at a very unstructured visual scene, such as a blue sky, with nothing more strongly patterned to distract you, you can often see the white blood cells moving in your blood vessels, precisely because they are moving rather than fixed in position on your eye. Moreover, when an optometrist shines a light into your eye to check your retina, the light projects the blood vessel image onto a different set of photoreceptors in the retina. Those photoreceptors respond to the image, and you can suddenly see the network of blood vessels in your eye. Conversely, if you were to wear special goggles that corrected for the tiny jittery movements of your eyes so that an image from the outside world would be truly stabilized on your retina, the image would appear to fade away as your photoreceptors adapted to its constant presence. A related biochemical process is involved in light adaptation, the process by which ....blarh blarh OK.. me again here (and a couple more layers of neurons) sounds interesting, funny enough I'm actually educated also and can explain anything with a little imagination, but sorry this does not quite explain it. I will continue looking. I'm not a Shmuck. PS Chevy Chase???

Hello, Thanks for the post GaryLeo. What you started describing at the beginning of this discussion is very similar to what I get, however there are a lot of differences in some later descriptions such as colour, patterns and so on. I simply see bright pinpricks of light, very small and very erratic, dissapearing and appearing. I can focus (to a degree) on individual specks and follow them, but not for long. Even though I have to keap unfocused I still have a sense of distance and can concentrate on specks closer to or further from me. I think the whole blood vessal idea is a little dodgy Hmmm. I would like to know if the above is the EXACT same as what you see. If there are any differences, please post and describe! Cheers again Clayton

Hi Guys, Did anybody get the bottom of the random little darting specks of light that I also see on a fine day outside whenever I unfocus my eyes at will. I'm just interested to know what they are and thats all! I have emailed GaryLeo and Losfomot and have had no reply. Its very interesting. I have yearly eye examinations/photographs and they are fine. This whole floater flasher thing is something entirely different and My blood pressure is fine!. Any sensible reply appreciated. Clayyts
